Also they construction and arra my improved u lamp socket in general permitso attachment of a bolicin shape, so and at thesame time willfserve lgmeilt of guard in associa-tionl with the reflector, preferably parathat the latter can be-used to hold the soclretin the handle portion;l thus preventing the socket from either turni ing out.

Referring 4to thedrawings and particularlyto Figures l toi? inclusive, 12 represents a perforated shell `arranged inlt'ubular form and preferably made of .1m/etal.4 j This shell can, if desired, be readilymade of sheet metal in which ythe perforations- 13 can be Figure 1 punched out so; that allfportions between the. v perforations. are integral.

The perforatedv shell v12 'is removably ittedaround and detachably 'attached to the e or base'portion of a enlarged front end H 15 which pass through bayonet slots or notches16jformed in one 15 enter screw threaded meta-ly u vthehandle V14, said lhandle being preferably ,portion of j `end of theperfor'ated shell. n These screws g inserts 17 in ing material.-v

handle. so as tobe rmly embedded therein u,

removedk or inthehandle, as.wouldhappenif the-screws were inserted directly in the wood. The

handle 11 yis counter-bored as shown at 18y fortheA reception ofa socket 19- which may have suitablecontacts andterininals forthe attachment of electric conduit, or. cables, and 4wiressuch as shown at 20, and topermit a i. to the shell, the pins counter-bore 18 is somewhat deeper than actually required for the socket 19 as shown in Figure 1 and a space 21 is thus provided to permit the electrical cable or cord'20 to be tied in a knot as shown at 22 so as to prevent any pull on the wire 2O from detaching the wire from the connections in the socket; it being noted that the knot 22 1sl larger than the passageway 23 in the handle 14 through which the wire 20 enters.

rlhe socket 19 has a shoulder 24 which prevents the socket from going too deeply into the counter-bore and thus insures thearrangement above specified. A reflector plate 25 surrounds and extends in front of the outer end of the socket, and may besecured to the forward end of thehandle 14- by screws 26. rlfhis reflector plate serves; as a means for retaining the socket within. the counter-bore, though if the reflector' is: not desired` for use, the socket can be secured within the kcounter-bore of the handle by screws or other suitable means. rThe reflector plate 25 is preferably -made parabolic: and not only-serves to hold the socket but. also reflects or projects light from the lamp,` bulb 27 as is obvious from the construction illustrated. A hook 28 which is shown inv dot-and-dash lines in Figure 1 and in full lines in Figure 8 may be arranged to extend laterally from the shell adjacent the outer end, and may be employed for hooking and suspending v the vstructure when desired.

Whenrequired, a perforated'cap 29 is fitted to the outer end of the shell 12 so as. to telescope therewith as shown in Figure 1; said cap being illustrated in detail in Figures 4 and 5. As shown, the cap 29 coin-l prises a single piece of sheet metal embossed to a flatteneddome form, with substantially cylindrical rim portion connected to the center by radially extending ribs, which are separated by the elongated triangular perforations. lhen the cap 29 is used the outer endr of the shell is provided with pins 30l 'adapted to be projected through bayonet slots or notches` 31 in the cap 29. The cap 29 also has on its rim a number of spring pressed locking fingers 29a securedv at one end to the cap and having opposed free hooked 'ends 29h bevelled or tapered 'in front, and thus adapted to spring into the innermost portions of the bayonet notches 31. 'The part 32 of the rim of the cap is depressed so as to provide recesses 33 through which the pins 30 can pass when the cap is first moved into connection with the shell 12. By partly rotating the cap relatively 30 will bend the locking fingers 29aL due to their engagementwith Athe hooked ends 29b until the vpins move back of beveled shoulders 30a of said hooked ,ends yas clearlyv shown in Figurev` 6. The lingers29ia will then spring into the position shows' Figur@ .6 and thereby'hold the @er against accidental rotary movement rela-r tively tothe shell 12, and the cap will be' firmly attached to the shell.

l have illustrated the cap 29 as provided with a hook 34 so that if desired the structure when the cap is present may be attached by means of the hook 34 or the device may be suspended by means of the hook 28 if the cap is not present, as shown, for example, in Figure 8. In all other respects the construction illustrated in said Figure 8 is similar to that above described and l have therefore given corresponding parts similar reference numerals. f lt will be iin-- derstood however that if desired thek struc ture shown in Figure 1 may be provided with a hook 28 so that even though the guard is constructed to receive the cap, if the cap is not used the hook 28 will serve to support the structure.

In Figure 9 l have shownrmy invention as applied to a conduit boX. As illustrated the conduit box base structure 35,1nay be provided with angles or clips 36 having headed pins or screws in the bayonet slots 16. ln all other `re spects the construction of the perforated guard shell may be as above described and l have therefore given corresponding parts similar reference numerals.

In Figures 10 and 11 l have shown my improvedv perforated guard shell applied as a protectorv for a lamp 38 which is arranged adjacent to and substantially parallel with a wall 39. In this constructionl have shown the shell 12 provided at-its bottom with an extension 40 which as illustrated consists vof a curved strip 441 adjacent the wall 39 and two overlapped angularly disposed strips 42 which are joined to the strip 41 and yto the bottom end ofthe perforated shell 12.

By making my improved guard in the form of a perforated shell it is rendered practically universal and may be employed with very little change to suit numerous re- 37 adapted to engage quirements not previously possible in a convenient manner with lamp guards ofinterwoven wire or ythe like. Furthermore by having the attachment by means of the bayonet joint such as shown in Figures 1 to 9 inclusive, the perforated guard shell can be quickly and neatly attached to asupporting structure either of a portable or fixed chars acter. The provision of thel removable cap with the spring lock bayonet connection prdvides a protection for the end of the shell and also permits the removal of the lamp bulb if it is not desired to disconnect the shell from its supporting structure.

Having thus described my invention, what. I claim as new and desire to secure by Letters Patent isz- 1. Apdevice `of the character described includi'ng a handle 'having a bore therein; a socket tting-within'said bore; a lftector surrounding said socket; and means for' securing said reflector to said handle, said reflector having a portion in front of the outer end of the socket whereby the socket is held in the bore and the removal of the reflector permits the socket from the bore.

2. A perforated lamp guard; a cap for closingan end thereof, said guard andI cap jointly providing a'bayonet slot and a projection for entering said slot; and a spring locking finger having one end secured and the other end free and provided with a hook having a tapered shoulder and adapted to spring into the inner portion of'said slot and resiliently hold said projection therein.

3. A device of the character described including a handle having a bore therein tapering inwardly; a lamp socket fitting within said bore; a reflector surrounding said socket and having a portion in front of a part of the socket; and means for securing said reflector to the handle, said bo-re being deeper than said socket whereby a space is provided adjacent the inner end of said socket, said handle having a passageway leading from said tapered portion of the ready removal of the space whereby an lelectric wire can extend formed in saidr wire and drawn tight between saidl socket and the passageway. v

. 4. A device of the character describedincluding a handle having a-bore therein; a socket fitting within said bore; a reector surroundingsaid socket; means for securing said reflector tothe front end of the handle within the confines of its peripheral surface, said reflector having a portion in front of the outer en'd yof' the socket is held in the .bore and the removal of the reflector permits the ready removal of the socket from shell lamp guard secured around the vperipheral surface of said front end of the socketl whereby the Y the bore; ande a perforated handle which includes said socket; .substantially as described.
